studentdatabaseapp (NEW)

Package name: studentdatabaseapp
Example main class: StudentDatabaseApp

Purpose

The Student Database App is a simple console program to enroll and manage multiple students during a run. It collects student information, records enrolled courses, calculates tuition per student, accepts payments, and prints a final summary including remaining balances.

Core features added

• Prompt the user for how many students to add.
• For each student:
  • Get student name.
  • Get student year (e.g., Freshman, Sophomore, Junior, Senior, or numeric year).
  • Get courses the student is enrolling in (comma-separated or entered one-by-one).
  • Calculate course fee = number_of_courses × COURSE_FEE (COURSE_FEE is a constant in the code).
  • Accept a payment amount and calculate remaining balance (fee − payment).
• Print each student's summary: name, year, list of courses, total fee, paid amount, and balance.
• Simple input validation for numeric entries (counts, payments).
